(Jefferson, OR) -- Police say the arrest of a Jefferson man who allegedly shot and killed his neighbor's dog has turned up nearly two-dozen guns. The Marion County Sheriff's Office says since July, 41-year-old Jeremy Cornwell's family members have shared concerns for their safety because of his escalating behavior and access to guns. Cornell was living in a shed, and Marion County SWAT served a warrant arresting Cornwall on a charge of Aggravated Animal Abuse. A search of the shed uncovered more than 20 guns.
